GEORGE KAUTZ, or ALBANY, AND LEwIs A. KAUTZ, OF HOOSICK FALLS, NEW YORK.

MASONS HAWK.

I SPECIFICATION forming part of Letters Patent No. 416,410, dated December 3, 1889.

Application filed March 5, 1889.

To all whom it may concern:

Be it known that we, GEORGE KAUTZ, of Albany, in the county of Albany and State of New York, and LEWIS A. KAUTZ, of I-Ioosick Falls, in the county of Rensselaer and State of New York, have invented a new and useful Improvement in Masons Hawks, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in masons hawks, and has for its object to provide a hawk having a table of uniform thickness, and in which a handle may be expeditiously and conveniently attached thereto or detached therefrom; and a further object of the invention is to provide a means whereby, when the handle is attached to the table, it will be as firmly and rigidly secured thereto as though it constituted an integral portion of the same.

The invention consists in the novel con struction and combination of the several parts, as will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the hawk. Fig. 2 is a central vertical section through the device. Fig. 3 is a perspective view looking at the under side. Fig. 4 is a central vertical section of the hawk, illustrating a modified form of fastening device; and Fig. 5 is a perspective view of the said modification.

In carrying out the invention the table 10 of the hawk is provided with a perfectly smooth flat upper face and a centrally-conveXed under surface 11, whereby the center of the table is of greater thickness than the ends and the ends are of uniform thickness, rendering the said table much less liable to warp than in the old style, in which the under or back surface of the table is beveled.

In the under face of the table 10 at the center a dovetail groove 12 is produced, extending from end to end, capable of receiving a block 13, which block, when inserted in the said groove, will form and serves to complete the contour of the back of the table, as best illustrated in Figs. 2 and 3.

Serial No. 301,934. (No model.)

A plate 14 is attached to the table of the hawk at the back to project outwardly and downwardly therefrom at the center, as best illustrated in Fig. 2, which plate consists of a rectangular base 15, having attached thereto or integral therewith a vertical member 16,in the outer edge of which vertical member a T-slot 17 is produced.

The inner face of the back strip 13 of the hawk-table is recessed to receive the base 15 of the plate 14:, and the vertical member 16 of the said plate is made to project outward and downward through the slot formed in the said strip, whereby the recess 17 in the plate is beneath the table. The plate is so attached to the strip 13 that the said strip may be readily slid in the dovetail groove 12 of the table.

The handle 18 is provided with a central bore enlarged at the upper end to receive the head of a bolt 19, the body of which bolt passes downward through the bore proper and out beyond the lower .end of the handle, which lower end is provided with a recess 20, to receive a wing-nut 21 and to admit of the said nut being screwed upon the projecting end of the bolt to a contact with the base-wall, as shown in Fig. 2. In the upper end of the handle a diametrical slot 22 is cut of sufficient depth to receive the projecting ends of the plate member 16.

In attaching the handle to the table the rigidly and securely attached to the table.

member 16 of the locking-plate 14 is more or less triangular and adapted to receive asimilarly-shaped nut 22, which corresponds to the head of the bolt 19. (Illustrated in Fig. 2.) The bolt 19 in the modification is threaded at both ends, and the inner end is screwed into the said nut 22, as shown in Fig. 4.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with the table of a hawk and a plate attached to the outer side of the same provided with a downwardly-extending slotted member, of a handle provided with a diametrical slot to receive the projecting member of the plate, a headed bolt loosely mounted in the handle, and a lock-nut capable of binding the handle, bolt, and plate together, substantially as shown and described.

2. The con1bination,with the table of a masons hawk and a plate secured to the under side of the said table at the center, provided with a vertical outwardlyextendin g member having a T-slot produced in the outer edge, of a bolt having a head capable of entering the slot in the plate,a handle bored to receive the said bolt and provided with a diametrical end slot to receive the said plate, and a locknut capable of being secured upon the outer end of the bolt, substantially as shown and described.

3. In a lnasons hawk, the combination, with a table having a central transverse dovetail groove in the under face, a strip secured in the said groove, and a plate countersunkin the inner face of the said strip, having a member extending downward and outward at a right angle thereto provided with a T-slot in the outer edge, of a bolt having a head capable of entering the slot in the said plate, a handle bored to receive the said bolt, and a lock-nut, all combined for operation substantially as shown and described.

4. In a masons hawk, the combination,with

a table provided with an edge of uniform GEORGE KAUTZ. LEWIS A. KAUTZ.
